T. natunensis Smith, Ann. Mag. Nat. Hist. 1894, vol. xu. p. 458, pl. xvi. fig. 7. 
Hab. Hulule, North Male Atoll. 
I cannot distinguish the few specimens from the above locality from this Philippine 
form. Other examples were described from the Natuna Islands under the name of 7. 
natunensis. 
8. Melampus castaneus (Miihlfeldt). 
Melampus castaneus Mihlfeldt: Pfeiffer, Mon. Auric. p. 30, for synonyms and references ; 
Smith, in British Museum Monog. Christmas I. p. 58, pl. vu. fig. 18. 
Hab. Inguradu, North Mahlos Atoll, on the shore. 
This species occurs at Christmas Island, also the Samoan and Hawaiian Islands—and 
doubtless in many intervening localities. Other species of Melampus also have a very 
extended range. 
9. Leptopomoides halophilus (Benson). 
Cyclostoma halophilum Benson: Pfeiffer, Conch. Cab. ed. 2, p. 241, pl. xxx1. figs. 29—31.

Hab. Heddufuri, South Mahlos Atoll; Fainu, North Mahlos Atoll; Midu, Addu Atoll. 
A few specimens from the above localities appear to be inseparable from this species. 
They are smaller than Ceylonese examples and may not be full-grown. Being in fresh 
condition they exhibit a few spiral lirae, which apparently become worn away or very 
indistinct with age. Most specimens are of a brownish horn-colour with a single reddish 
line below the periphery. Occasionally this line is above the periphery, or it may be 
entirely absent. The Ceylonese specimens are generally of a richer brown colour and inclined 
to be longitudinally streaked. They also exhibit a pale zone above the infraperipheral line, 
a feature sometimes observable in the shells from the Maldives. 
10. Melania tuberculata (Miiller). 
Melania tuberculata Reeve, Conch. Icon. vol. x11. pl. xi. fig. 87; pl. xvi. fig. 110. 
Hab. A freshwater pool, Hulule, North Male Atoll. 
Brot? gives the following distribution of this well-known species. N.E. and W. Africa, 
Madagascar, Mauritius, India, Ceylon, Syria, Persia, Mesopotamia, Arabia, Siam, Java. It 
also occurs in Australia. Only young examples, about 16 mm. in length, were obtained at 
the Maldives.
